Nutrient Deficiencies: Leading Cause Of Red Geranium Leaves


Nutrient deficiencies are a major cause of red geranium leaves. It’s essential to conduct soil testing and maintain a consistent feeding schedule to prevent this issue. A lack of nitrogen, phosphorus, and magnesium often leads to leaf discoloration, as does excessive potassium.

Inadequate sunlight, improper watering, and pests or disease may also contribute to the problem. To avoid nutrient deficiencies, make sure your plants receive adequate light, water, and nourishment. It’s necessary to pay attention to your plant’s warning signs, such as yellow leaves, before the leaves turn red, as this can indicate an issue.

Checking your plant’s roots and ensuring that it is not situated in a too-small container are two additional steps that can aid in preventing red geranium leaves.
